About Immaculate Conception · Arlington, Washington
Immaculate Conception Parish is a Roman Catholic parish located at 1200 E 5th Street in Arlington, Washington, in the Archdiocese of Seattle. The parish also serves as the home base for St. John Vianney Mission in nearby Darrington, and together the two communities form the core of Parish Family 5 under the Archdiocese's Partners in the Gospel pastoral plan. The parish offers Mass on Tuesday evenings, Thursday mornings, and Saturday vigil, with the Sacrament of Reconciliation and Eucharistic Adoration scheduled around those liturgies. The parish supports faith formation for children and youth, the Society of St. Vincent de Paul for outreach to neighbors in need, and a wide range of family-life and community ministries.

Why belong here
Immaculate Conception offers the warmth of a small-town parish in the Stillaguamish valley, with a manageable schedule of weekday and weekend Masses, regular confession and Eucharistic Adoration, and the personal attention that comes from belonging to a tight-knit Catholic community. Worshippers here are also linked to a wider parish family that includes St. Mary in Marysville, St. Cecilia in Stanwood, and the St. John Vianney Mission in Darrington, opening up additional Mass times, faith formation, and ministry opportunities across north Snohomish County. Outreach through the Society of St. Vincent de Paul, faith formation for children and youth, and a sister-parish bond with Christ the King Church in Bungoma, Kenya, give parishioners concrete ways to live their faith beyond Sunday Mass.

Parish Family 5 (Partners in the Gospel)
As of 2024, the Archdiocese of Seattle grouped Immaculate Conception into Parish Family 5 under its Partners in the Gospel pastoral planning initiative. The four parishes and missions share a single pastor and collaborate on faith formation, liturgy, and outreach, while each community keeps its own identity and Sunday worship schedule. The unified schedule lists Mass and Confession times across all four worship sites so families can worship at whichever church fits their week.
